Variability of the metaphyseal-diaphyseal angle in tibia vara: a comparison of two methods.

Although Levine and Drennan described the metaphyseal-diaphyseal angle (MDA) in tibia vara using the lateral border of the tibial cortex, there is a lack of uniformity in the literature. The authors measured the MDA using both the lateral border and the center of the tibial shaft in 132 knees (66 patients) with bowleg deformity and examined whether there is a significant difference between these two measurements. At angles < or =11 degrees there was significant variance between the two methods.

Left ventricular mass change during treatment and outcome in patients with essential hypertension.

Background: It is uncertain whether reduction of left ventricular (LV) mass during antihypertensive treatment predicts reduces cardiovascular complications of hypertension.

Methods: A total of 172 prospectively identified patients with essential hypertension without complications of hypertension at baseline and follow-up echocardiograms 5.5 +/- 3.

Inverted arcuate osteotomy and external fixation for adolescent tibia vara.

The purpose of our review is to describe and report results of a surgical technique for the treatment of adolescent Blount's disease. We retrospectively reviewed the results of 15 inverted arcuate osteotomies combined with external fixation. The inverted arc provides a proximal and stable osteotomy that can correct deformity in three planes.

Comparison of classification of the severity of hypertension by blood pressure level and by World Health Organization criteria in the prediction of concurrent cardiac abnormalities and subsequent complications in essential hypertension.

Objective: To determine whether classification of the severity of hypertension according to the World Health Organization (WHO) system, which utilizes additional clinical and laboratory findings, is superior to classification by blood pressure level alone in predicting prognostically important cardiac structural abnormalities and the risk of subsequent complications in asymptomatic subjects.

Design: Two-hundred and twenty adults with uncomplicated essential hypertension underwent baseline clinical evaluation and echocardiography; 88% were subsequently followed for a mean of 11.6 years.

Development of the acetabulum and hip: computed tomography analysis of the axial plane.

Acetabular growth and development in the axial plane was evaluated by computed tomography (CT) scan. One hundred seventy normal hips of children ranging in age from 6 months to 17 years were evaluated for axial acetabular index, anterior and posterior center-edge angles (CEA), and acetabular anteversion. The acetabulum deepens and becomes increasingly spherical with time until the age of 13 years.
